Do you really know what oil filter four is?

In this day and age, there are CEOs and successful entrepreneurs everywhere in my social circle. A classmate whom I haven't contacted for 3 years suddenly appeared on my social circle and became an internet celebrity, scaring my baby to death!

What are engine oil, filter, air filter, air conditioning filter, gasoline filter, etc? When should it be replaced? The importance of automobiles. Below, the editor will provide answers in sections.

1Engine oil

Engine oil, also known as engine lubricating oil, is divided into fully synthetic and mineral engine oil. Its main function is to lubricate and reduce wear, assist in cooling and temperature reduction, seal and leak prevention, rust and corrosion prevention, shock absorption and buffering of the engine. Commonly known as the "blood" of cars, mineral engine oil is replaced every 5000km, and synthetic engine oil is replaced every 8000-10000km

It should be noted that if your car has not been used for more than 3 months, a comprehensive inspection must be conducted before use, and the oil and oil filter should be replaced according to the inspection results. It is absolutely not easy to understand that not driving does not require changing the oil and oil filter, and not using it necessarily means it is good.
In addition, please do not blindly believe in original engine oil, as no manufacturer produces their own engine oil. Original engine oil is usually OEM, and you only need to choose to use synthetic or mineral oil during maintenance.

2. Oil filter element
The function of the oil filter is to filter out impurities, gum, and moisture in the oil, and deliver clean oil to various lubrication parts. Equivalent to the "kidney" of a car, whether it's me or it, it shows the importance of this oil filter element. It is emphasized that the filter must be replaced together with the engine oil, and the mileage and time of maintenance are the same as changing the engine oil. For replacing the filter, the editor recommends using a reputable brand with good quality and good reputation.

If you replace the engine oil with a better one and use a cheaper filter, of course, its filtering effect will be greatly discounted. As the saying goes, good goods are not cheap, cheap goods are not good. Since you have already replaced the good engine oil, don't be stingy. Generally, a good filter cartridge is between 50-100 yuan, and the average quality is around 30 yuan

3. Air filter cartridge
The engine needs to suck in a large amount of air during operation. If the air is not filtered, the suspended dust in the air will be sucked into the cylinder, which will accelerate the wear of the piston group and cylinder. Larger particles entering between the piston and cylinder can cause serious "cylinder pulling" phenomenon, which is particularly severe in dry and sandy working environments

The air filter is installed in front of the carburetor or intake pipe to filter out dust and sand particles in the air, ensuring sufficient and clean air enters the cylinder.
If the air filter is in a good air environment, it can generally be replaced every 30000 kilometers or even longer; If driving in an environment with poor air quality for a long time, it will need to be replaced within 2 months. In the maintenance manual, for general urban vehicles, the air filter should be replaced once a year or every 20000 kilometers (whichever comes first)

4. Air conditioning filter element
The air conditioning filter (air conditioning filter element) is mainly used to filter the air entering the cabin from the outside to improve the cleanliness of the air. The general filtering substances refer to impurities, small particles, pollen, bacteria, industrial waste gas, dust, etc. contained in the air. The effect of the air conditioning filter is to prevent such substances from entering the air conditioning system and damaging it, providing a good air environment for passengers in the car and protecting the health of passengers in the car

Generally, air conditioning filters need to be replaced twice a year, once in spring (before prolonged use of the air conditioner in summer), and once in autumn (before prolonged use of the air conditioner in winter). If your air conditioner has an odor, in addition to replacing the air conditioning filter, it is recommended that you perform a deep cleaning of the evaporator box

Of course, if you are in a city with poor air quality (such as Hebei, Beijing, and other cities with severe smog), the frequency of replacement may be higher. During each maintenance of the oil and air filters, the price of the air conditioning filter element may be slightly higher compared to the machine filter and air filter element. In addition, air conditioning filters can be divided into ordinary and anti haze types

5. Gasoline filter cartridge
Gasoline filter, abbreviated as air filter, can be divided into fuel injector type and electronic fuel injection type. Its main function is to filter impurities in car fuel, making the fuel supplied to the engine for combustion purer

A typical gasoline filter needs to be replaced at least once every 20000 kilometers or 1 year. For car owners, replacing the gasoline filter is very important. Insufficient power and high fuel consumption may also be caused by the fuel filter not being replaced for a long time. The main reason is that after the filtered "gasoline" is burned, the engine is prone to problems such as carbon deposition, dead fire, and decreased power.
When the filtering effect of the gasoline filter is not good, the gasoline injected into the combustion chamber is definitely not completely burned. Due to incomplete combustion, the power cannot reach the ideal speed, so the car owner naturally presses the accelerator deeply. In this case, fuel consumption follows suit
